Concha Velasco studied dancing and became an actress in a revue with Celia Gámez. In 1954 she made her film debut with roles in several minor films. At the end of the regime of dictator Francisco Franco she worked with director Pedro Olea, among others, in higher-quality films, such as Torment (1974) and Pim, Pam, Pum… Fire! (1975), which gave her a better reputation. One of her biggest successes was Teresa de Jesús (1984) in which she played Santa Teresa de Ávila.
